Trebek, who is in town filming the National Geographic World Championship at Google headquarters in Mountain View, appeared at Wednesday's taping in a leg brace and told the audience that he had fallen and hurt his leg while chasing a burglar at his hotel in San Francisco, a Google spokeswoman said.

The 71-year-old is doing well, according to Jeopardy senior publicist Phil Zimmerman, who declined to comment further on the incident.

San Francisco police responded to a report of a burglary at the San Francisco Marriott Marquis, at 55 Fourth St., around 3 a.m., police Lt. Troy Dangerfield and the hotel's director of sales and marketing Leslie Duncan said.

Dangerfield said two hotel guests were sleeping when a woman entered their room and stole a number of items, including purses, wallets and cash.

One of the guests awoke and saw the woman leaving the room, then jumped out of bed and chased her down the hallway, he said. During the chase, the victim fell and injured his leg.

The woman continued to run until she was captured by hotel security guards, who notified San Francisco police, Dangerfield said.

Police arrested 56-year-old Lucinda Moyers on suspicion of burglary and receiving stolen property, he said. No other suspects are believed to be involved.

Officers found several of the stolen items near the hotel ice machine, but no cash was recovered, Dangerfield said.

Duncan could not comment on how the woman got into the hotel room, saying the case is still under investigation, but said “safety and security are paramount to our guests.”

She also said that the woman arrested was not an employee of the San Francisco Marriott Marquis.
